Lifting slings are devices made of mesh, chains or ropes, of a certain length, used for lifting heavy objects, connected to a crane or hoist.
Slings can be flat, round or endless, and can also be used alone to lift the load. When required, lifting slings can be used in combination with grade 8 chain components.
Slings, compared to chain, are lighter and their smooth surface does not damage the goods being lifted. They are also more flexible and can be made in different formats. Slings are manufactured in different colors and make it easy to recognize the maximum load for each sling. Slings must be manufactured in accordance with current standards. The safety factor is 7:1.
ROUND SLINGS WITH OR WITHOUT LOOPS?
Depending on the type of goods, different types of slings must be used. Protections may also be used to protect the slings from damage by the goods themselves.
CE MARKING
Since January 1, 1995, lifting slings must be CE marked. This is evidence that the slings comply with the EU machine directive. The slings must be supplied with maintenance instructions and certificate of conformity to production.
WHAT IS THE 7:1 SAFETY FACTOR?
Safety factor means that the lifting tool has a breaking strength 7 times the maximum load. For example, if a round sling has a maximum load of 2 tons and a safety factor of 7:1, it means that the breaking strength cannot exceed 14 tons. It is very important that the maximum load is never exceeded.
CALCULATION OF THE WORKLOAD LIMIT
The different colors on the slings represent theworking load capacity of each sling.
To calculate the rated working load limit for each configuration, please see the table below.
